Ugh, no!

for descr, attr, colours in [
        ('normal',      'image',        'Normal'),
        ('highlighted', 'highlight',    'Highlighted'),
        ('selected',    'select',       'Selected')]:
  colourlist = getattr(MainWindow, 'Colors%sList' % colours)
  ## ...

To be honest, there's so much regularity in that table that I'd consider
generating it from a shorter list.  This would obviously involve
refactoring something else to eliminate the image/normal asymmetry.  I'd
also consider making the ColorsMumbleList attribute collection into a
dictionary.

Note that my columns are aligned to 8-column tab stops for easy
maintenance (although my editor has used physical spaces rather than
tabs).
